The 2021 Virtual Outstanding Student and PhD candidate Presentation (vOSPP) Award is awarded to Matthew Hayward for the poster/PICO entitled:

Matty Hayward is a PhD student in the department of Civil and Environmental Engineering at the University of Auckland, New Zealand. His research focuses on the numerical modelling of wave hazards generated by volcanic activity such as submarine eruptions, flank collapses or entry of pyroclastic density currents.

The awarded PICO presentation describes the verification of a non-hydrostatic multilayer numerical scheme for use in modelling waves produced by variable size disturbances from laboratory-scale experiments up to field-scale explosives, with further application on to modelling waves from a hypothetical submarine explosion at the caldera under Lake Taupō, New Zealand.
